AX LEP'NUTH SPECIFICATION forming part of Letters Patent No. 761,415, dated May 31, 1904.

\ A li ti fil d November 2 19( )3. Serial'No. 179,525. (No model.)

To all whom it may concern:

Be it known that I, HENRY A. SHERMAN, a citizen of the United States of America, and a resident of Fremont, county of Sandusky, State of Ohio, have invented certain new and useful Improvements in Axle-Nuts, of which the following is a full, clear, and exact description, reference being had therein to the accompanying drawings, in which Figure 1 is a side elevation of an ordinary Vehicle-axle providedwith my device; Fig. 2, a perspective view partly in section; Fig. 3, a'perspective viewof the end of the axlespindle with the nut removed, and Fig. 4 an end View of the nut.

. The object of this invention is to provide a simple device for holding the wheel upon the.

axlev in such a manner'that the liability of loosening the axle-nut will be obviated, as more-fully'hereinafter set forth.

I In the drawings, a designates the axlespindle, which is provided at its outer end with the usual reduced threaded portion 6.-

In the end of the spindle proper is a segmental notch 0, whichis cut down to a level with the threads on the extension 6, and formed in the threaded extension I) is a guidegroove 01, which extends centrally into said notch c.

The nut e is of the usual form'except that at its upper edge-it is provided with an annular outward-extending flange f, rounded on its outer surface. A washer g is attached rotatively to this nut by a flange it, extending outward and downward, so as to loosely clasp the annular. flange f on the inner edge of the nut. On the inner face this washeris provided with a segmental lug t, which is shaped to nicely fit into the notch c in the'end of the formed a radial lug or rib j, which is located coincident with the center of the lug t and extends inward to the inner end thereof.

It will be observed that the nut is free to rotate independently of the washer and that the washer is prevented from rotating by the engagement of the lug 71 with the notch 0. The groove d is simply a guiding-groove serving to properly direct the segmental lug i into the notch 0, while the-notch and lug i take all the .strain exerted by the tendency of the wheel to loosen the washer. By thus utilizing the groove in the threaded extension for guiding purposes only and the lug z' for locking purposes it will be observed that said grooves may be made so shallow as not to weaken the threaded extension and the lug 4 and its receiving-notch may be made as large as necessary to take up the strain without weakening the spindle.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

In combination, with an axle-spindle having a threaded extension and a notch formed in the spindle proper adjacent to said exten-.
